Improvement in fly-traps



UNTED STATES PATENT QFFICEn FRANK M. CARROLL, OF KENDALLVILLE, INDIANA, ASSIGNOR OF ON E-HALF HIS RIGHT-TO JOHN LAMB, OF GRAND RAPIDS, MICHIGAN.

IMPROVEMENT IN FLY-TRAPS.

Specification forming part of Letters Patent No. 185,724, dated December 26, 1876; application tiled May 31, 187e.

To dit whom it may concern Be itknown that I, FRANK M. CARROLL, of Kendallville, in the county of Noble and State of Indiana, have invented certain new and useful Improvements in Fly-Traps and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference heilig had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speeitication.

The nature of my invention consists in the construction and arrangement of a flytrap, as will be hereinfter more fully set forth.

In the annexed drawing, Fig. lis a front elevation. Fig. 2 is a rear elevation. Fig. 3 isa central vertical section on linewx, Fig. l 5 and Fig. 4 is a detail view of the bristles.

A represents a box of such dimensions as to be placed in a window. The outer side ot' this box or frame is covered with netting B. The inner side is formed of a series of inclined glass plates, C C, set in such a manner in the sides ot' the frame that the lower edge of each plate will be on the outside of, and below, the upper edge ofthe plate immediately below it, leaving a narrow space or opening, a, between them. A row of bristles or hair, b, is attached to the opposite surfaces of the overlapping edges of the glass plates C C, as shown.

The trap being placed iu a window, the room should be darkened, so that no light can get in, except through the trap. The flies are attracted by the light, and pass through the passages a into the box, from whence they cannot escape, as their return is prevented by the protruding hair b on the glass.

ln lieu ot' the glass plates C any transparent or translucent substance, or wire-cloth, or other loose cloth, may be substituted; and many things may be used in place of' the hair.

At the lower end of the box is a hinged door, D, which allows of the removal of' any substanceinside. Suitable bait is to be placed in the bottom of' the box.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'Ihe box or frame A, provided on one side with netting B, and on the other side with a series of inclined overlapping glass plates, C, or their equivalent, forming entrances a, and the obstruction b, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I aiix my signature in presence of two witnesses.

FRANK M. CARROLL.
